SPECIFICATION forming part of Letters Patent No. 263,745, datedSeptember 5, '1882. Application nien May 12, lass. `(No model.)

To all whom it may concern Be it known that I, EDwYN ANTHONY, a subjectof the Queen of Great Britain, residing tem poraril yin the city of NewYork, in the State of New York, have invented anew and lusefulImprovement in Printing-Machines, of

which the following is a specification.

The object of my invention is to simplify the delivery and foldingapparatus of printingpresses which print from two rolls ofipaper and insuch a way that both the rolls are printed on alike and that the samematter is printed on each side of a roll. Provided the rolls issueprinted on in the manner just described, my invention is applicable,whatever be the nature of the printing mechanism.

Figure19 illustrates one such printingmechanism, and Fig. 18 (which istaken from the specification of British Letters Patent No. 1,127, year1875) exhibits another. Figs. lto 6 show the wayin which the webs mustissue in order that my invention can be applied. Figs. 7 to 1-1illustrate the various stages which the 'webs pass through in theprocess of association when the papers are to be delivered folded. Allthese figures `referto eight-page papers. Figs. 15 to 17 are similarfigures for a twelve-page paper.

Considering the case of an eight-page paper, the forms may be placed onthe form-bearing cylinder or cylinders, so that after the webs have beenprinted on both sides each will come out printed, either as indicated inFig. 1 or in Fig. 2, (forms on sidewise,) or as in Fig. 3 or Fig. 4,(formson lengthwise.) ln the latter case, when we wish to deliver thepapers folded, it is better to arrange the forms so that the webs maycome out printed as shown in Fig. 5 or in Fig. 6, instead of asin Figs.3 and 4.' ln Figs. 1 and 3 each portion A B is repeated twiceconsecutively, and likewise G D. lf th e portions are repeated three,four, or more times, what follows will still obviously apply, andit isneedless to illustrate such cases by separate diagrams. Heretofore' thetwo webs have been cut, folded, and delivered separately when they issuefrom the printing mechanism printed on in the way hereinbeforedescribed. By -bringing them together, as hereinafter explained, wegreatly reduce .the mechanism required for the above purposes.

We will first consider the case of open delivery. After each web hasbeen printed continuously on both sides we run them together, bringingeither of the two webs onto the top of the other one. When the webs arecut before printing they must 'of course be brought together after thecutting; but when they are cut after printing itis usually moreconvenient to bring them together before cutting, because then one pairof cutting-cylinders will serve to cut both webs. Whether the webs comeout, as in Figs. 1, 2,3, or 4, we bring the samepart of one web onto thesame part of the other. Thus the A Bs of the one web must fall onto theA Bs of the other, andthe C Ds of the one onto the G Ds of theother. Thetwo webs thus brought together may now be treated as one web anddelivered in lany suitable way.

When we deliver folded we must consider separately the cases of theforms on sidewise and of the forms on lengthwise.

For-ms on sidewisaln addition to the transverse cuts,the Webs must becutlongitudinally along their central lines in any suitable way. Thedotted lines in the figures indicate where these transverse andlongitudinal cuts are to be given. These may be made while the webs aretogether, so that one apparatus will serve the purpose. We may adopteither of two plans for bringing them together. 'Ve may treat each webseparately and bring in any suitable way the A Bsof each web onto the CDs ofthe same web. (See Figs. 1 and 2.) Each web will now A B, orgreater, if the motion of the sheets has been accelerated. We cantherefore, by properly fixing the distance of travel of the two webs,make them run in one stream, as illustrated in Fig. 9, au interval beingbetween consecutive papers if the motion has been accelerated. If theweb be now severed longitudinally along the dotted line, Fig. 9, theneach half-sheet A H, together with the halfsheet underneath it, makes upa complete paper, and, similarly, each half-sheet G B, with thehalf-sheet underneath it, makes up a complete paper. rl'he stream thusshown must now be conducted to a folding apparatus suitable for foldingpapers, reaching it in the form IOO indicated. lf preferred, the streamon either side (say A H of Fig. 9) may be turned the other side up inany suitable way before it reaches the folding mechanism. In this casethe stream would reach the folders in lthe shape-indicated by Fig. 10,and the folding mechanism must of course be correspondingly modified.The other way of bringing the webs together is the following: Let theone web (call it No. 1) run constantly in the same path. Let the'A Bportions of the other (call it No. 2) run on to the top of the C Dportions of No. 1, and its C D portions underneath the A B portions ofNo. 1. This may be accomplished by running the C D portions of No. 2 (wesuppose No.2 web to be running above No. 1 web) beyond the foldingapparatus and returning them underneath web No. 1, or by turning the C Dportions out of their path by a suitable apparatus and bringing themback underneath No. 1. The webs will now be in the state shown in Figs.9 or 10, as the ease may,

ing case; but no longitudinal cutting is re-l quired. The dotted linesin Fig. 18 indicate where the transverse cuts are to be made.

Treating each web separately, the A Bs go onto the G Hs and the G Dsonto the K Ls. The webs are'then traveling as in Fig. 11 or Fig. 12,and, being run into one stream, become as in Fig. 13 or (similarly tothe case previously described of the forms on sidewise) No. 1 web may berun constantly in one path, and theA Ds of web No. 2 run onto the Gr Lsof No. 1 and the Gr Ls of No. 2 run underneath the A D`s of No. 1. Thewebs having by either plan been brought into the state shown in Fig. 13,they may be either so conducted to the folding apparatus, or the ABs maybe first turned` the other side up by any suitable mechanism, so thatthe papers will go to the folding mechanism, (of course suitablymoditied,) as shown in Fig. 14:.

Devices for cutting a web longitudinally or transversely, for separatingsheets into two paths, for bringing two or more sheets together, Src.,are well known, and to such devices I herein make no claim.

Figs. 1S and 19 illustrate one of the methods of treatment hereinbeforementioned. After printing on both sides, each web is conducted bysuitable rollers to the same pair ot' cutting-cylinders, C D, Fig. 18.Issuing at L, they need not again be separated when the delivery isopen, but they may go direct to the delivery apparatus. Since, however,the sheets are running solne one way up and some the other, it will benecessary (if it is desired to deliver them all lying the same way up)either to separate them into two streams and deliver them onto separateboards, or to pass half of the sheets through a suitable reversingmechanism, and thus bring them the same way up as the other half. Thepath of the webs to the left of the cylinder() D (shownin Fig. 18)refers to the case of folded delivery. When they are to be folded, then(treating them in one of the ways hereinbefore explained) the web A willgo in one path to the folding mechanism, alternate portions of the otherweb, B, going with it, and alternate portions being diverted andconducted by suitable rollers and tapes in a path, E F G H N, till theyrejoin web A underneath the same.

Fig. 19 illustrates another printing mechanism and shows in detailarrangements for bringing the webs together, as hereinbefore eX-plained. Each of the form-bearing cylinders K K L has placed on it a setof eight forms, (each Vcontaining one of the eight pages which make upthe paper in question.) The rolls are printed on one side by passingbetween cylinders Gr and K, and another by passing between cylinders Eand L, as the figure indicates. It is obvious thatthe forms may bearranged on the cylinders so that the webs shall pass between thecutting-cylinders G D printed on as shown in Figs. 2, 4, or 6. Tapes (asindicated by the dotted line pass between C and D) and around therollers p p, their ends'c c being run together by suitably-placedskewpulleys. The knife carried by one of the cylinders C D has smallportions cut away at intervals, and the aforesaid tapes are placed sothat when the knife comes around they may run between the saidintervals.

P is a guard which enters grooves cut for the purpose in the rollers ee2. Its object is to prevent any possibility of either of the websgetting between e and e2.

Tapes pass around b', d', b2, (12,6, and e2, and also round d C and Y2D. The last two sets of tapes are fixed so that they may pass betweenthe before-mentioned intervals ofthe knife.

The rollers l2 l m m2 touch a circle whose center lies in the commontangent of d d2, and the pair of rollers b b2 oscillate in an are of acircle whose center is coincident with that of the circle previouslyspoken of. Their oscillation is timed so that they deliver sheetsalternately between Z2 l and m m2, and their'oscillation may completethe severance ofthe web, which the knife has not entirely effected.

The foregoing remark only applies when the webs are printed on asshown'in Figs. 2, 6, and 15. 0f course when the web is as shown in Figs.l and 5 the oscillation must be timed so as to let two consecutivesheets pass between l l2, and then two between m m2, and so on, and,similarly, three, four, or more consecutive sheets must pass at eachoscillation if three, four, or more sheets are traveling eonsecutivelythe same way up.

A set of tapes start from af, pass round l, r, s, fw, and y', and thenceto a. Their ends al al mustof course be run together; buttheircourseprevious to doing so will depend on the folding mechanism F, which maybe of any suit-` able kind and placed somewhere in the space IOO IIO

Ils

aca-aas f Y s l r s ze y. :A set of tapes starting from Z2 pass round'r,s, w', and y?, and are thence returned by suitably-placed rollers to l2.Tapes also pass round m, their endsff being ultimately run together,their previouscourse depending on the folding mechanism.-

A guard is fixed withits endsrunning into grooves in the rollers mzt.Its object is to.`

prevent the oncoming web and sheets from coming agaiust'theroller.m2,whose motion is in the contrary direction. VThe course of the webs maynow be easily traced. The web A passes between the cylinder D and thedottedline tapes, thence round e2 and along between the tapes f and a.The web B passes between C and the dotted-line tapes, thence between d"cl2 to the oscillating rollers b b2. The sheets delivered bythelast-inentionedrollers between m and m2, passalong between the tapesf and c above the web A, the sheetsdelivered between Z2 Z' pass round rs w, then between y l1./2, and finally between the tapes fand a, butlunderneath the web B. A

The completion ot' the severanceof the web 4Aand the folding may now bedone in any suitable way. When the other method of treatmenthereinbefore mentioned is adopted separate pairs of cutting-cylinderswill be required l for each web, and the rest ofthe treatment be whathas already been described for that case.

When it is desired by the mechanism of Fig. 19 to deliver thesheetsunfolded all that is necessary is to remove the tapes c', which passround the rollers 29, to connect the cylinderD and theroller e2 bytapes, similarly to the way in which the cylinder C and the roller d2are connected, as hereiubefore explained, and to stop the oscillationot' the pair of rollers b b2, rollers m m2. The distance of travel ot'the webs must of course be such that the same parts come together asthey pass between the cylinders C and D. Thus both webs will passbetween e2 and C, d? and d', b2 and b', and m2 and m', finally issuingbetween the tapes aj', whence they must be conducted to any suitableopen delivery apparatus, as hereinbel'ore explained.

The other method hereinbefore described of treating an eight-page paperwhich is to `he delivered folded is illustrated by Fig. 20.

There are two pairs ot' cutting-cylinders, C D, one pair for each web.The course of the webs till they reach the said cylinders is shown inthe drawings, and it may be easily traced. Considering the left-handportion of the tigure, the rollers a/c rotate with the samesurface-velocity as do G and D, while all the rollers to the left of thesaid rollers rotate with a somewhat greater surface velocity. There is aslight interval between a( a2, while b b2 are close together, so thatthey may bind the sheets and complete their severance, which has notbeen entirely effected by the cuttingcylinders a C as also c2 D areconnected by tapes, indentations being made inthe knife carried Vby thecutting-cylinder, so as to admit of their free passage, b a', also, b2u? are from the drawings. Tapes also grooves in them for that purpose,)round which the tapes pass. The roller b is also provided with loosepulleys, round which the -tapes indicated by the dotted line pass. The

course ot' these last-mentioned tapes is clear pass `round j' c',another 'set round g c hf, and another round c2 52p c2. The ends z eofthe tapes which pass round the rollers d2 e are of course ultimatelyjoined, their path before they do so depending on the subsequent foldingmechanism, &c. Tapes pass round c2, d2, e2, and o2 (to the right of thefigure.) The tapes whose ends are denoted by v a: are of courseultimately joined, their path bet'ore they do so depending on thesubsequent folding mechanism, 85C. prevent the oncoming sheets touchingthe roller b', which rotates in the direction eon trary to their motion.

P Q are guides or switches, which must be operated on by cams or othersuitable devices. They must be capable of oscillation round the centersof c 02, respectively, so as to be in the position shown in theleft-hand side of the fgnrevhile` two sheets are being collected in thecircuit formed by the rollers f g c', and then move to the positionshown in the right hand of the figure, so as to permit the two collectedsheets to pass out between the rollers c2 d2,

A similar mechanism to that just described is shown to the right ot' thefigure.' It seems unnecessary to more particularly describe the saiddevices, because I do not herein claim them, and any suitable device forcollecting sheets in pairs may be used. Thus the web B issues frombetween d2 02, and thence between e e2, traveling as indicated in Figs.7, 8, 11, or 12.` Similarly, the web A issues from between c2 d?, (righthand of the tigure,) passes along R S T V, and thence between the tapesa: z. The length of R S T V must be adjusted so that the two webs, whichbecome one stream when they get between the tapes, (whose ends aredenoted bywa) will be traveling asindicated in Figs. 9 or 13.

I do not herein claim the method just described, because I intend tomake a separate application for Letters Patent for the same.

1t is clear that when the delivery is unfolded the foregoing methods areapplicable to all papers, whatever the number of their pages, and thatsimilar methods apply to papers of a larger number of pages than eightwhen the papers are delivered folded. For example, suppose, in printinga twelve-page paper, the forms are arranged so that the webs come outprinted as shown in Fig. l5. Then, treating each web separately, webring, by any suitable way, the G Hs onto the A Bs and the K Ls underthe O Ps. Each web will then be traveling as shown in Fig. 16, A Bconsisting of two sheets and G D of one sheet, and, similarly, O Pconsisting of two sheets and M N of one Between fb a guide is placed tolIOO IIO

sheet. Now let No. l web run constantly in the same path, and let the ANs of No. 2 Web run underneath the C Ps of No. 1 web, and the C Ps ofNo.2 web run on the A Ns of No. 1. The Webs Will then be running` as inFig. 17. As before, they may-` be taken in that state to the folders; orthe O Ps may be first turned the other Way up, so as to bring bothstreams the same Way up.

The mechanism for thus treating a twelvepage paper may be such as isshown in Fig. 19, with the addition of mechanism forlongitudinallyseverng each web (along the lines indicated in Fig. 15)and of mechanism for afterward cutting transversely the so-severedcentrai part of the web and laterally' transferring alternate portionsof it, respectively, onto the two so-severed outside portions of theweb, all before the cylinders C and D, Fig. 19, are reached. v

What I herein claim as my invention is- The combination of mechanism forprintingr two Webs (so that both sides of leach web are printed onalike) with mechanism for cutting the Webs and associating alternateportions of 2 5 one of the Webs with the upper and alternate portionswith the under side of the other web, all substantially as described.
